如何用Java連接Aurora MySQL

本篇文章給大家分享的是有關如何用Java連接Aurora MySQL，小編覺得挺實用的，因此分享給大家學習，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著小編一起來看看吧。

以下是使用mysql-connector 連接Aurora for mysql：

Workbench 訪問Aurora，跟mysql方式一致，如： Aurora.example.rds.cn-northwest-1.amazonaws.com.cn

用戶名：root

密碼：root

Eclipse 開發首先在maven添加依賴，如下：  

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.15</version>
</dependency>

源代碼：  

package Aurora.test;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class ConnectAurora {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
                        //聲明Connection對象
                        Connection con;
                        String driver = "com.mysql.cj.jdbc.Driver";
                        //URL指向要訪問的數據庫名mydata
                        String url = "jdbc:mysql:// Aurora.example.rds.cn-northwest-1.amazonaws.com.cn:3306/db3";
                        //MySQL配置時的用戶名
                        String user = "root";
                        //MySQL配置時的密碼
                        String password = "root";
                        //遍歷查詢結果集
                        try {
                            //加載驅動程序
                            Class.forName(driver);
                            //1.getConnection()方法，連接MySQL數據庫！！
                            con = DriverManager.getConnection(url,user,password);
                            if(!con.isClosed())
                                System.out.println("Succeeded connecting to the Database!");
                            //2.創建statement類對象，用來執行SQL語句！！
                            Statement statement = con.createStatement();
                            //要執行的SQL語句
                            String sql = "select * from fileindex";
                            //3.ResultSet類，用來存放獲取的結果集！！
                            ResultSet rs = statement.executeQuery(sql);
                            System.out.println("-----------------------------------------------------------------------------------------------");               
                            System.out.println("------------------------------------------------------------------------------------------------");  
                            System.out.println("| "+ "id" + "\t" +" | "+ "app_id"+  "\t" +" | "+  "文件名字"+ "\t" +" | " + "文件地址"+ "\t" +" | ");  
                            System.out.println("------------------------------------------------------------------------------------------------");                          
                            String APP_ID = null;
                            String id = null;
                            String address = null;
                            String school = null;
                            while(rs.next()){
                                //獲取stuname這列數據
                                id = rs.getString("ID");
                                //獲取stuid這列數據
                                APP_ID = rs.getString("APP_ID");
                                address= rs.getString("File_Name");
                                school=rs.getString("File_url");
                                //輸出結果
                                System.out.println(" | "+id + "\t" +" | "+ APP_ID +" | "+ "\t" +" | "+address +" | "+ "\t" +" | "+school +" | " );
                                System.out.println(" ------------------------------------------------------------------");  
                            }
                            rs.close();
                            con.close();
                        } catch(ClassNotFoundException e) {   
                            //數據庫驅動類異常處理
                            System.out.println("Sorry,can`t find the Driver!");   
                            e.printStackTrace();   
                            } catch(SQLException e) {
                            //數據庫連接失敗異常處理
                            e.printStackTrace();  
                            }catch (Exception e) {
                            // TODO: handle exception
                            e.printStackTrace();
                        }finally{
                           System.out.println("數據庫數據成功獲取！");
                        }
                    }
}
